Describe forward-biased diode?
A specific amount of current is allowed to flow through a diode. If the current passing through the diode exceeds this specific value, the diode gets heated and is likely to be damaged. Therefore, in the biasing circuit of a resistance which limits the current passing through the diode within its specific value is called Forward biased diode. ANSWER: A forward bias diode is just a diode that it is conducting in the forward direction. Positive to anode and negative to cathode
Why do we get current in reverse bias?
because semiconductor diodes are not perfect insulators when reverse biased. if you want a diode that is a perfect insulator when reverse biased, use a vacuum tube diode.
When both junctions of NPN diode are reverse biased then the diode is in which mode?
Transistor will be in OFF mode.
What is the leakage current of zener diode?
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
What is the PIV rating of diode?
A diode will provide saturating current if it reaches its Piv. What it should be well at least 1.5 of the applied reverse voltage. For AC at least 2 times to insure that the peak REVERSE voltage is blocked
When both junction of npn diode reverse biased the the diode in what state?
reverse biased
Why silicon controlled rectifier doesn't work in reverse biased condition?
Because when reverse biased it behaves like any other rectifier/diode.
What will happen if a diode is connected to capacitor?
the diode when forward biased will conduct and during reverse biased condition(generally doring reverse biased condition ckt is open mens no current flows;when register is connected)current flows but during reverse biased condition 1--for sometimes initially current flows due to discharging of capacitor. 2--then ckt will be having no current
How is a non-conducting diode biased?
A nonconducting diode is biased in the reversed direction (reverse polarization).

What is the significance of piv of diode?
The PIV (Peak Inverse Voltage) rating of a diode is the maximum voltage that you should apply to it in the reverse biased condition. Exceeding this voltage can destroy the diode.
Why do we get current in reverse bias?
because semiconductor diodes are not perfect insulators when reverse biased. if you want a diode that is a perfect insulator when reverse biased, use a vacuum tube diode.
When the both junction of NPN diode is reverse biased then the diode is mode?
